It's the same system. It doesn't fail alone. Didn't we both previously see 
issues with the interaction of tests due to the other of tests, that previous 
tests left things in the environment that affected later tests?

Oh :-( Does "./python -m test test_io --fail-env-changed -v" fail?

[issue41717] [AIX] test_io: files was modified by test_io: (@test_6488748_tmpæ) on POWER6 AIX 3.9

[STINNER Victor]

New submission from STINNER Victor :

'@test_6488748_tmpæ' is likely TESTFN_NONASCII which is exposed as 
test.support.os_helper.TESTFN, but test_io has many many tests using TESTFN.

https://buildbot.python.org/all/#/builders/330/builds/20

0:06:47 [130/425/1] test_io failed (env changed) (1 min 8 sec) -- running: 
test_concurrent_futures (31.1 sec)

Warning -- files was modified by test_io

  After:  ['@test_6488748_tmpæ']

Since build 1, 19 days ago:

If someone is able to reproduce the issue, please attempt to identify which 
test method leaks the temporary file using the command:

./python -m test.bisect_cmd test_io --fail-env-changed -v

After 10-20 minutes, the command should give the name of a single method which 
creates the temporary file.
